What were once called zoos, are now referred to as "animal enclosures" but only if they comply with the safety and concern of the animals. This usually involves more comfortable and scenic spaces created for specific individuals and groups that facilitate their safety, physical and mental health. Themes along these lines have grown in prevalence.

Enclosures themselves can be as large as needed such as in the case of elephants and other large animals or small as in the case of aquariums or butterflies. Each type of animal/creature has special requirements.
